Abstract: Natural slopes are often observed to have a concave, convex, or a combination concave/convex profile, yet constructed slopes are traditionally designed with planar cross-sectional geometry. In this paper, the stability of ...

Abstract: Although the availability of discrete-element method (DEM) codes has improved, the need still exists to solve simple verification problems to obtain an understanding of these codes. Different DEM codes may have subtle ...

Abstract: Terzaghi’s consolidation theory assumes strain in soil due to applied overburden pressure is small, and permeability and thus the coefficient of consolidation (Cv) remain constant during consolidation. Although valid for ...

Abstract: Collapse of the residual soil over bedrock cavities often occurs during construction in karst terrain, particularly when the thickness of the residuum is reduced during excavation. Even if an estimate of the strength of ...

Abstract: Constructed slopes are traditionally given a planar form. However, natural slopes are more likely to be concave in cross section. In addition, laboratory and computational studies have demonstrated that concave slopes yield ...

Abstract: A new device for cyclic testing of large size interfaces between structural and geologic materials and rock joints is described. Test results are reported for a sand‐concrete interface, and are used to express shear stress ...

Abstract: Mechanistic pavement design procedures based on elastic layer theory require the specification of elastic moduli for each material in the pavement section. Repeated load tests yielding a resilient modulus are frequently ...

Abstract: To evaluate the effect of mining-induced subsidence on a proposed coal refuse embankment, a two-step, combined empirical/finite element (FE) analysis was conducted. A maximum ground surface subsidence profile was obtained ...

Abstract: A simple thin‐layer element is developed and used in a finite element procedure for simulation of various modes of deformanon in dynamic soil‐structure interaction. The constitutive behavior of the interface is defined by ...

Abstract: Mechanistic-empirical pavement design methods for flexible pavements are based on the assumption that pavement life is inversely related to the magnitude of the traffic-induced pavement strains. These strains vary with the ...
